Design studies of a quasi-optical mode converter and output system for a second harmonic sub terahertz gyrotron

This paper presents the design studies of the output coupling system of a 460 GHz, 50-100 W, CW, second harmonic gyrotron for medical spectroscopy. During this course, the design studies of an advanced dimpled-wall quasi optical launcher (QOL), non-linear taper and RF window will be carried out.
